Malahini trailer

Postby Hercdrvr » Thu Apr 20, 2017 9:43 pm

I found this galvanized trailer for only $200. What was a great bargain is turning out to be a fair amount of work. New bearings, seals, springs (one was broken), lights, bunks, tires,guide poles, I think that's about it. Don't know what a new trailer costs but into this one for about $500. Boat is about the max size the trailer can handle.

The tongue weight was too light so I shifted the axel aft about 18 inches. I didn't weigh the tongue but I have to grunt to lift it, it's probably close to the magic 10% of trailer on the tongue.

Mounted the lights up high out of the water. Maybe now the bulbs will last more than one season. The lights are a couple of feet forward from the back of the trailer, I hope it's legal this way. I didn't glue the piping together, used a screw at the joints so it can be disassembled if needed.

Figured it was kind of important to keep the axel perpendicular to the direction the trailer is traveling so I measured. Don't know what kind of of tolerances are required but I'm within a 1/16". If my new tires wear out in 500 miles ill get a little more serious with my measurements.

I love your truck!

By UK standards $500 all in sounds pretty good and at least you know everything's sorted.

I think I'd be concerned about the bunks not extending back to the transom, though, particularly with that big motor hanging off it and unsupported. I'd want the transom supported by the bunks and something solid to fix a transom saver to. Maybe I'm just over-cautious....

Sproggy,
In the pictures the boat is not all the way forward to the bow stop. The bunks are even with the transom when the boat is against the bow stop.
Even having new bearings and the works I still carry an extra set in my truck. Having a bearing go out somewhere in west Texas is no fun. Been there before.

Ah, right - I missed that it wasn't all the way forward.

As for bearing failure, I've been there too - motorcycle front wheel bearings (with 3k miles on them) disintegrated in one of the more remote parts of Spain, no cell signal. Not great. Met some interesting people as a result, though :wink: New is no guarantee of anything.

I just went out and looked, the bunks stop about 3 inches from the transom. IS THIS BAD? I could move the bow stop forward.

If the bunks are directly under battens then you might be OK. But if you can move the bow stop forward to get the transom actually on the bunks I'd still do it.

Then you can move the wheels forward again to keep the right nose weight :)

Matt,
I think, as Sproggy mentioned, you will want to have a transom saver to support the motor while trailering.
It looks like the trailer frame does not extend far enough back. Maybe some extension can be added for that purpose.

Yes, a transom saver is very important to spread the weight of the motor between the trailer and the boat. Many transoms have been wrecked when a bouncing trailer and motor over-stressed the boat. A roller on the back of the trailer is also a good idea to guide the bow off the trailer and can be the spot to set the transom saver.

Ditto on everything said above, lots of good advice. I learned a couple of them the hard way.

I bought a new trailer, it was right at a grand with tax so youre still about half of new.

Interesting. My Yamaha 4 stroke says to trailer it in the down position.

Maybe that's something to do with engine oil draining into places it shouldn't be (past piston rings?) if towed tilted. Not an issue with 2-strokes.

I think you're right. Sometimes we have to be careful here and not mislead people. We all have to learn about our equipment.
